SU672629A1 - Device for displaying vector images on television receiver screen - Google Patents

Description

The invention relates to automation and computer technology and can be used in output devices and displaying graphical information. There are known devices for displaying graphic information on the screen of a television receiver, containing an input register, a ferrite matrix, coordinate counters with decoders, amplifier 1. The disadvantage of these devices is the impossibility of rotating the symbol. The closest to the technical nature of the invention is a device comprising a symbol register and a turn register connected to decoders, a control register, a sweep counter, a permanent memory reminder connected to a decoder 2 J. This device allows the symbol to be rotated 90 °. A disadvantage of this device is its limitations. 1 directions of century of rtp eNUn code symbol. - The aim of the invention is to paciiaip the application of the device by displaying differently oriented vectors. This goal is achieved by the fact that two switches, two 2I-OR elements, two 1 pulse splitters and two pulse generators, the inputs of which are connected to the control register, are inserted into the device, respectively. The outputs from the first and second switches, each output connected to one of the inputs of two 2I-OR elements, the outputs of which are connected respectively to the first and second distributors of pulses connected to the memory unit, the rotation angle decoder is connected to the first pulse distributor, two switches and electric mentaki 2I-OR. This allows you to display differently oriented vectors for a given character code and different angles of rotation of the character. FIG. 1 is a diagram of the proposed device; FIG. 2 — Differently oriented vectors for different line frequencies. The device contains a control register 1, a generator of 2.3 pulses, switches 4.5, elements 2I-OR 6.7, a register of rotation 8, a symbol, a decoder 9 of the angle of rotation, a register 10 of simol, a decoder of symbol II, distributors 12, 13, memory block 14.

The device works as follows.

. The input information enters the register of 8 rotations of the character, to the register of 10 characters. The signal from the output of the angle of rotation 9, whose input is connected to the output of the angle register. Turn B, goes to switch 4.5, elements 2I-OR 6.7, and to the control input distributes Igshul -.sov 12. Register 10 code is connected to the character decoder 11, which is the choice of a defined character in memory block 14 ,
